Update audit configuration. All fields are optional — only provide the ones you want to change.
AI agents use audit_config_update to create or update resources in Truenas — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Truenas environment.
The tool creates or modifies audit configuration settings, which is characteristic of Write operations. It is reversible (fields can be changed back), not destructive, and does not execute code or move money. Severity is medium because misconfiguration of audit settings could reduce security logging visibility, but the action itself is not immediately dangerous and can be corrected.
From the tool's definition Tool name contains 'update' and description states 'Update audit configuration'; this modifies system settings reversibly without deleting data or executing arbitrary code.
Documented attack patterns abuse exactly the kind of access audit_config_update gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Truenas, and nothing reaches the server without passing your rules. This is the rule we recommend for audit_config_update:
{
"version": "1",
"default": "deny",
"tools": {
"audit_config_update": {
"limits": [
{
"counter": "audit_config_update_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}audit_config_update stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Update audit configuration. All fields are optional — only provide the ones you want to change. It is categorised as a Write tool in the Truenas MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Truenas MCP server in PolicyLayer and add a rule for audit_config_update: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Truenas. Nothing to install.
audit_config_update is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the audit_config_update rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for audit_config_update. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
audit_config_update is provided by the Truenas MCP server (spranab/truenas-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Truenas, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
